6 Claims.

This invention relates to fastening means.

More particularly it is concerned with novel fastening means for use on es'cutcheons or the like type of plate applied to a lavatory pop-up waste fitting.

Heretofore it has been a problem to assemble with a lavatory or other plumbing fixture an escutcheon in which the application thereof is relatively easily adjustable to the fixture and in which the means of assembly simple and cheap.

It is therefore an important object of this invention to provide a fastening means for an escutcheon or the like, preferably consisting of a round pressed metal base plate having a raised and beveled, spiral shaped edge forming a coarse thread for engagement with an inner similarly formed recess of the escutcheon.

It is a further important object to provide for the assembly of a simple clamp bar to a base plate-preferably by means of a plurality of machine screws, or similar holding means and thereby facilitate the attachment of the escutcheon or cover with or without the lever actuated waste mechanism.

It is aflfurther important object of this inVention to provide a simple assembly for, a lavatory or other similar fixture and in addition to permit a more secure fastening, relying upon the inherent resilience of the base plate combined with multiple screw assembly to accomplish such latter advantage.

Other objects and advantages will become clearly apparent upon proceeding with a description of the article considered in light of the accompanying drawings, in which Fig. 1 is a fragmentary sectional assembly view of an escutcheon embodying my invention,

Fig. 2 is a fragmentary plan view.

Fig. 3 is a sectional view taken on the line of Fig, 1.

Fig. 4 is an enlarged exterior view of one form of novel base plate.

Fig. 5 is a plan view of the structure Fig. 4.

Fig. 6 is a modified form of the base plate.

Similar numerals refer to similar parts in the several views.

Referring now to Fig.

shown in 1, the escutcheon or cover l is shown to be of generally hemispherical form,

although for purposes of this invention it need not necessarily be of such shape. It is provided with the fluted opening 2 within which the nonrotatable knob'3 is slidably movable. In order to provide for a substantial length to the fluted therewith is comparatively 111., assign or to Crane Cos I 7.

opening 2 theescutcheon' is preferably made with the skirt 4 extending within the hollow of the escutcheon. At the lower portion of the knob 3 the latter is apertured as at -5 to receive'the shank 6 of the'shouldered screw 1. Below the shoulder, the lower portion of the shank iiv is threaded asat 8, to which the rod '9 having the offset-head -por-- tion: H is suitably attached as indicated. The base plate |2,'as shown more clearly in Fig. 4 is provided with a raised and beveled; spiral shaped edge It which forms a thread for engaging the similarly formed spiral recess l4 ofthe escutcheon. The base plate edgesindicated at l5 are preferably smooth and free fromburrs and the base plate I4 is provided with two countersunk holes is to receive the flat machine screws l1 for threadedly supporting, the bar l8; the latter member spanning-the key hole aperture I9 of the fixture. The base plate is also provided with the aperture-20 to allowfor the. projection there'- through of the'rod 9. The offset portion ofthe rod 9 may be suitably attached to a closure member of waste outlet, not shown, as indicated at =2l. Thus by raisingand lowering the. knob 3-the drain outlet of a'plumbing fixture may be suitably controlled. l *It will thus be apparent that in such instances in whicha relatively frangible plastic is employed, the novel base plate and assembly of my invention constitutes a substantial improvement over the prior art. It will also be apparent that depending upon the thickness of the plate l2 the escutcheon may be mounted with suitable resilience and flexibility, avoiding previous breakage and objectionable distortion.

It should of course be understood that a metal escutcheon or cover may be usedinstead of a plastic escutcheon. Also instead of having a pressed sheet metal construction for the base plate which on its periphery forms a full coarse thread, a modified form of flat base plate 23 may be used as in Fig. 6, having a relatively fine thread 24 on its outside edge to accomplish a similar result.

Thus a relatively simple and economical meth- 0d of attachment has been provided, However,

7 it will also be apparent that the specific structure may vary substantially and it is therefore the desire to be limited onlyby the scope of the appended claims interpreted in light of the prior art.
